Abstract
Abstract The invention relates to cooling towers of the type currently in use for cooling water and/or condensing exhaust steam as for example in association with nuclear or fossil fuel type power plants. Typically towers are very large and very high. The invention embodies an original concept for utilization of such towers, for example hyperbolic towers, for the generation of energy from wind and also for improving the efficiency of the cooling tower. In the exemplary form of the invention a large wind driven rotor is provided to be carried by the tower and to rotate around its axis at the position of the narrowed throat of the tower. Pressure is generated by the rotor and discharged through nozzles arrayed on the inside of the walls of the tower to augment and enhance the draft within the tower.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
In a structure of the character described in combination, a cooling tower of the type in which a vertical draft of air is produced for purposes of cooling water for condensing exhaust steam, means comprising a rotor carried by the tower at an elevated position and means whereby the rotor rotates around the vertical axis of the tower on the exterior thereof and is exposed to wind, the rotor being constructed whereby it is caused to rotate by prevailing winds, and means for transforming energy generated by rotation of the rotor.
Claim 2
Dependent Claim
91 words
In a structure of the character described in combination, a cooling tower of the type in which a vertical draft of air is produced for purposes of cooling water for condensing exhaust steam, means comprising a rotor carried by the tower at an elevated position and means whereby the rotor rotates around the vertical axis of the tower on the exterior thereof and is exposed to wind, the rotor being constructed whereby it is caused to rotate by prevailing winds, and means for transforming energy generated by rotation of the rotor.
Claim 3
Dependent Claim
28 words
Apparatus as in claim 1 wherein the tower is hyperbolic in contour having an upper portion of reduced diameter, said rotor being mounted substantially at said reduced diameter.
Claim 4
Dependent Claim
27 words
Apparatus as in claim 1 including circular trackway means surrounding the cooling tower and the said rotor having wheel means constructed to travel on the trackway means.
Claim 5
Dependent Claim
43 words
Apparatus as in claim 1 wherein the said rotor comprises a plurality of vane means having mounting means whereby the vanes are adjustable in orientation with respect to the adjacent surface of the tower and means providing for relative adjustment of the vanes.
